Question

Quizplus · Accepted Answer

Pearls result from biomineralization, which is the process by which living organisms produce minerals such as calcium carbonate or silica. Pearls are formed within the tissue of certain species of oysters and clams when a foreign object, such as a piece of sand, becomes trapped inside the shell. The organism then covers the object with layers of nacre, a crystalline substance that forms the lustrous surface of the pearl.
